Welp, after the impending (then canceled) closure of these forums, a cross-country relocation for me, and the release of 1.14... I'm back.
1.14's changes to villagers was very discouraging, as far as updating Stevian Villagers. Mojang removed full textures for each profession, and there is now only one base texture (face) for ALL villagers. So it seems Stevian Villagers for vanilla 1.14 is dead in the water. It might be possible using Optifine's random mobs to restore the variety of Stevian Villagers, but this would REQUIRE Optifine to work. Not everyone is keen on installing Optifine, especially since it is not yet compatible with Forge in 1.14.
So I'm at a loss as to what to do with Stevian Villagers at the moment. Input is welcome.
